(Un)Plugging Cooling Water Passages

One of the moulds for my Monotype Composition Caster, specifically the type U Lanston display mould fitted for 36 point body size, had completely blocked cooling water passages. This would seriously limit how fast the caster could run, even more

My Presentation from the 2012 ATF Conference

Someone recently asked about serial number locations on Monotype Composition Casters, and I knew I had a sort of list of where these were located. This information turned out to be in a presentation I gave at the 2012 American

Monotype Composition Caster Pot Temperature Controller

Over the past few months, I’ve had to replace the old Partlow temperature controller on the pot of my Monotype Composition Caster. On my caster the old mechanical controller has failed; each time I ran the caster I found that

Monotype Repairs: An Enclosure for a New Pot Temperature Controller

While using my Monotype Composition Caster recently, I’ve noticed that the pot temperature has been drifting. On several occasions I’ve found it to be quite a bit hotter than the setpoint, to the point where I had to select a

Air Compressor for the Monotype Caster

I’ve been using a compact air compressor to run my Monotype Composition Caster. The machine uses pneumatics to control what matrix it casts, when to start a new line, how wide to make the adjustable-width casts, etc. Originally the caster

A Cool-down Drool on the Monotype

I have recently taken another Monotype mould out of mothballs to use for casting a font of 6-point type. This is one of the moulds I got from Rich Hopkins’ tertiary storage, i.e. his garage. I had cleaned off the

A Good Casting Day

After much thought about my problem with second shot, and with little help from any manuals, I’ve got my caster to behave properly. The second shot problem was caused by an incorrect adjustment in the pump crosshead and linkage area.

Another Bad Casting day

Yesterday, I tried to cast another font of 12-point Caslon Old Style (Lanston 12-337E). The computer and pneumatics worked flawlessly, but the type kept misbehaving in the type channel. The caster seemed to be doing something known as a “second

A Little Monotype Alignment Conundrum

I recently cast a font of 12-337E Caslon Old Style from a 15×15 matcase using my Monotype computer interface. Upon rummaging around I also found that I had loose cellular matrices for the quaints in this font. That would be
